C++1x Multiple thread usage

thread_pool

A class which will create a pool of thread, you can determine how much threads to create or determined by the hardware performance itself. The thread_pool class used new c++1x features and make it easy to use.

    thread_pool pool(4);
    auto result = pool.thread_pool([](int process) { return process; }, 42);
    std::cout << result.get() << std::endl;

thread_safe_queue
A thread safe queue which used condition variables to try or wait to pop element of the queue.

thread_safe_stack

A thread safe stack which used condition variables to try or wait to pop element of the stack.

thread_sequence

Aim to solve the problem of multiple threads printing natural numbers in order.

    thread_sequence seq;
    seq.start(10, 3);

After running, the console will print like following:

    Thread 1: 1
    Thread 2: 2
    Thread 3: 3
    Thread 1: 4
    Thread 2: 5
    Thread 3: 6
    Thread 1: 7
    Thread 2: 8
    Thread 3: 9
    Thread 1: 10

high_resolution_timer
High resolution timer without errors.
```c++
auto tp = std::now();
high_resolution_timer t;
t.setInterval(& {
printf(“Frame:%d\n”, std::duration_cast:milliseconds>(std::now() - tp1).count());
tp = std::now();
}, 10);

t.sleep_for(1010);
t.stop();

>Console print:
```text
    ---100 ms
    Total: 1010 ms
